Upgraded the first of the year from a D80 to a D7000. Picked it up used at a local store, like new in the box with all orginal packing, and 5,500 clicks on it. Really enjoying it, learning, and taking a lot of pictures. Pulled it out last night to take pictures at fire drill and this is what I get:
Now all I saved by buying used is lost and on the weekend my daughter graduates from college I have to fall back to the D80, a saving grace since I was going to give it to her for graduation. Boy what a difference and I was so looking forward to using the D7k. Thanks for listening
frig that second shot made me cringe. Did you purchase any sort of warranty from the store you bought it from? I know it's used but a lot of stores will offer an extended warranty on used equipment
Roger, the owner, frequently posts here w/ lots of relevant insights under the name "RCicala".
Also, FYI, shutter count is almost irrelevant except for a bargaining lever. Some shutters last 800k, some fail at where yours did... just no telling, it's kind of random.
^ It's not an exact science, but there's definitely a strong correlation between shutter actuations and failure. It's not random when you consider the aggregate. If it were, camera manufacturers wouldn't have MBTFs, from which we have shutter life expectancies. The expectancy for a D7000 is 150k. While it is certainly possible to have a D7000 fail at 1k, the odds of this occurring are far, far less than those of it failing at, say, 200k, which makes the shutter count quite relevant indeed for anyone buying a camera to take pictures with.

I suppose we'll have to agree to disagree. I would not feel significantly more "safe" covering a wedding with a brand-new body than one with 200k.
Back to editing and other things that generate income...
In the meantime, I hope the OP enjoys shooting with a rented camera body that can shoot at ISO 1600 instead of the ISO 400 I tried to not go above when I had my D80.

I didn't purshase any extended warranty but I did contact Midwest Camera Repair today and will be sending it off. Just won't have it for this weekend.
If you really want one, rent it. Lensrentals has pretty cheap prices on the lower level bodies. Overnight shipping and you're good. Of course, you could rent any camera they have, should you desire.

here's an interesting site - not really collecting data on all cameras, but still interesting to see the bell curve of when most failures happen. Looks like a lot of cameras make it well past that 150k number, but then there also a few that die well before 5000 clicks
Thanks for the posts, I actually purchased it from MPEX and was just checking out their rental page. I'm temped to try A D800 but know my skills are not up to one yet, specially with no chance to test run it. Better stick to what I know and can afford.
Interesting data. However, I am not sure how credible the data are. For example, at least 4 people got over 8 million clicks on their 5DIIs, including the one used by the president of US!!

It's just a law of averages. As a shutter life wears on, it has a higher and higher chance of failing.
Sure you have the outliers on either end of the curve (very short and very long lives), but MTBF means just that -- mean time.
Statistically and logically speaking, a new shutter is more reliable than an older shutter. Most of our personal sample sizes are a whopping (1), however, making any data we gather completely irrelevant.
